一种基于区块链和边缘计算的物联网方案

A solution for internet of things based on blockchain and edge computing

物联网设备资源受限,需要使用外部资源,而集中式的云方案恰好可以为物联网提供充足的计算存储资源.但是受制于网络带宽等因素,云不能及时地处理大量的数据.云方案采用静态密码的验证和明文存储的机制,也存在着安全性问题.区块链技术的兴起,为解决物联网安全问题带来了新思路.边缘计算缩短了数据处理距离,增强了实时性.因此,本文将使用这两项技术,解决目前物联网中的问题.

The resource of the internet of things(IoT) devices is limited and external resources are needed.While a centralized cloud solution can provide sufficient computing and storage resources for the internet of things.However,the cloud cannot process large amounts of data promptly,due to some factors such as network bandwidth.The scheme based on cloud uses static password authentication and plaintext storage mechanism,thus there are some security problems.The emerging technology of blockchain brings a new idea to solve the security problems of the internet of things.And edge computing shortens the distance of data processing and enhances the real-time performance.Therefore,this paper will use these two technologies to solve the current problems in the internet of things.
